CVE-2024-28986Known exploitationNetwork attack vector

Authenticated command execution via unsafe Java deserialization

Published Aug 13, 2024 · Updated Oct 21, 2025

Deserialization of untrusted data in SolarWinds Web Help Desk 12.8.3 and earlier allows remote authenticated users to execute host commands. SolarWinds has not disclosed the affected class or endpoint; the application unsafely deserializes attacker-controlled Java data. SolarWinds could not reproduce unauthenticated exploitation, while successful authenticated exploitation runs commands with the service's host privileges.
